It was interesting to read all the submissions on this topic. What I have found is a close correlation between the number of weeks spent doing the loop and the total cost. In my case two of us spent 25 weeks on the loop and spent $18,260 which works out to $730 per week in 2006 dollars. In 2013 dollars adjusting for fuel costs of $4.50 per gallon it would be $924. An equivalent size trawler with four people aboard took 54 weeks on the loop and spent $990 per week in 2013 dollars. If you want to know more please email me for a PDF that has the details.
